The Role of Epigenetics in Fertility: Unravelling the Influence of Lifestyle and Environment

Epigenetics, a rapidly growing field of scientific research, has started to shed light on the complex processes influencing our health, including our fertility. Unlike genetics, which involves changes to the DNA sequence itself, epigenetics involves changes in gene expression — essentially, how genes are switched 'on' or 'off'. Intriguingly, these changes can be influenced by a host of factors, including our lifestyle choices and the environment we live in.

Epigenetics and Fertility

Research has found that epigenetic changes can play a significant role in fertility. These changes can affect numerous fertility-related processes in both men and women, from sperm and egg quality to embryo development and implantation.

Several lifestyle and environmental factors have been shown to cause epigenetic changes. These include diet, exercise, stress, exposure to toxins, and even ageing. For example, a diet rich in certain nutrients can influence gene expression related to fertility. Similarly, exposure to environmental toxins can cause harmful epigenetic changes affecting reproductive health.

Optimising Fertility through Epigenetics

So, what does this mean for individuals trying to conceive? The good news is that many of the lifestyle, environmental factors, and supplement choices influencing our epigenome are within our control. Here are a few suggestions:

• Eat a Balanced Diet: Consuming a nutrient-rich diet can support a healthy epigenome. Focus on whole foods, including fruits, vegetables, lean proteins, and whole grains. Certain nutrients, like folate and zinc, are particularly important for epigenetic processes.
• Maintain a Healthy Weight: Both underweight and overweight conditions can cause epigenetic changes that impact fertility. Regular physical activity and balanced nutrition can support healthy weight management.
• Limit Exposure to Toxins: Reduce exposure to harmful environmental toxins whenever possible. These can include certain chemicals, pollutants, and even substances found in some plastics.
• Manage Stress: Chronic stress can lead to a host of health issues, including negative epigenetic changes. Mind-body practices like yoga, meditation, and mindfulness can help manage stress levels.
• Consider Supplements: Certain nutritional supplements can support a healthy epigenome. For instance, folic acid (we recommend the more bioavailable form folate) and B vitamins play a key role in DNA methylation, an important epigenetic process. Omega-3 fatty acids, vitamin D, and selenium are other supplements known to support epigenetic health and fertility. 

Understanding the role of epigenetics in fertility offers a fresh perspective on our reproductive health. By making conscious lifestyle, environmental, and supplement choices, we have the power to influence our epigenome and optimise our fertility.
